No sign of any Asians returning here yet after the solar hiccup. Quite
a number of weakish DU signals did make it today though. Australians
heard on 549, 612, 774, 792, 828, 891, 1548 and good reception of KUAU
from Hawaii on 1570, which had been missing during the good Asian
conditions.
My initial impression of the band on Monday morning held up through closer
inspection of my FDM-S2 recordings: it was dismal indeed. Although I'll
take coastal DXing any day over inland, the "sea gain" effect still bows
down to the propagation gods.
Tuesday morning showed promise from around 1400

I find it interesting that a very similar BOG / receiving antenna discussion is
also going on with the Topband reflector.
There's a fair amount of belief that terminated loops in a phased array or just
a single double loop style (DHDL, DKAZ, Bowtie, Waller Flag) can deliver
Mostly quiet on the western front this morning, with a brief tick upwards just
before 1450UT. Although signal levels were still suppressed, a couple of

IN its basic sense, the name "BOG" came from "Beveridge -on-Ground", and indeed
one of adequate length should behave similarly.
I don't know either of the two people you mentioned, but any of my interactions
with 160 meter guys have resulted in some very strange ideas

Thanks Chuck; I knew I could bring you out of the woodwork.
There's been a fair bit of hand-waving on the topband list about the
BOG over the years, partly because anecdotally, either they "don't
work", or that they have very good F/B. K2AV has done a lot of
measurements, and seems to conclud
My experience is exclusively on a sand beach. We found early on that a normal
ground wouldn't work. We ultimately ended up with a fan of 4 radials through,
IIRC about 220 ohms. We haven't been able to use BOG's since Hurricane Sandy
several years back. We had one running up the coast ( 37 degre
I don't see the self-terminating thing.
It seems to me (unscientifically) that the losses are maybe 5 to 7 dB. That's a
far cry from the 30 or more dB loss in a properly terminated system.

Have you had success terminating a BOG Russ? (supposedly it is ~200
ohms, rather than the raised Beverage's ~450 ohms).
I think some have found that it is self terminating, to a degree, as
there is quite a bit of loss on reflected signals.
best wishes,

Thanks to two awesome Finnish DXers (Mika and Mauno) for taking the time to
assess my 702 kHz UnID language recording from 1604 UTC this morning, and give
their expert opinions that this is Arabic from the BBC transmitter in Oman
(8,615 miles/ 13,849 km). This is far and away the best DX catch e
Didn't the discussion also cover whether the hum increases in
intensity as Chongjin fades down, and decreases as it dominates the
frequency? I believe that increasing hum with increasing Chongjin
signal strength would indicate that the hum is part of Chongjin's
signal, rather than due to the
Or could the hum be just heterodyne caused by 50 Hz difference between
Chongjin tx and Heilongjiang? I checked via a Japanese receiver and I
don't see strong side carriers, which would be typical for mains hum
otherwise.

It isn't a dumb question because the answer is yes and no. If you terminate a
BOG at one end, that should more focus the reception pattern in favor of the
terminated end. If you're looking for stations from the N, then terminate at
the N end. In the event that the desired result is an antenna wh
Dumb question --- Do BOG's get a termination?

Thanks Colin,
This morning's session was an absolute blast here-- both 675 and 711-VOV with
S9 peaks, 918-RNK putting on a concert of Cambodian music at a strong level, my
702 unknown language UnID suddenly pounding in at S9, etc. And as a bonus, we
get to miss the political nastiness in the ma
I see what you did there...
Needed the smile.
Happy mid-terms everyone!

160 meters, being above the AM/MW band could be effective at somewhat
shorter distances than for AM/MW, but 150-200' isn't really a BOG (
Beveridge on Ground ) it's a longwire. A BOG needs to be upwards of 500' I
would think. I've used BOG's on MW/AM ranging anywhere from 500' to 1200'.
The main di
I've used BOGs that were 800 - 1000 feet on MW, and they worked very well.

IRCA,
BOG users, how long do you make yours? I keep hearing from other Hams
that for 160m between 150 to 200 feet. I seem to remember hearing on
here about some that were much longer.
Thanks,
